GASOLINE TANK CAP LOCK Filed Oct. 5, 1929 Inventor V C, Fama;

A iiorney Patented Oct. 21 1 930 7 r gnnnonin, oE'rALATKA, Honing-1w"- i 7 f This invention relates to gasoline an ap 'lo'ck's and-more particularly toidevicesof this nature ofthe' type wherein'a cage or hood "pivotally 'niounted on-the gasoline tank or :theneck thereof'in a manner to enclose the cap to preventthe unauthorized removal thereof friorn'the tank.

" An important object of invention is to prov'ide in a lmann er' ashere'inafter set "forth, agasoline tank cap lockof the aforementioned a character which may be expedit-iously mounted inposition on the tank without the use of securing elements which ferent diameter.

Other objects of the invention are to provide a lock of the aforementioned character which will be simple in construction, strong,

i aligned bores" extending th V passage of a clamping bolt'6 which projects snsorirn n rmm cnr LocK "laterally beyond the outer edges of one of said lugs or ears'and' has threaded thereon h nut-"Z.

. vTheadjacent ends of the clampingring 4 are further provided with doWnwardly'and forwardly projecting horizontally disposed extensions 8 and?) which a-reclan pecl firrnly together to; constitute a iaita'rybase when 5 the ring is clamped around-the" neck 2. The

Otherobjects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a top plan view showing a gasoline tank cap lock constructed in accordance with this invention, the same being shown in position over the cap. I

Figure 2 is a side elevation thereof.

Figure 3 is a fragmentary rear elevation showing the end o1nt which connects the clamping ringand, the cage or housingcarrying ring. 7 a i Referring to the drawings in detail, the reference character l designates a portion of a gasoline tank for use on automobiles having an upstanding externally threaded neck 2 providing an inlet for supplying gasoline to the tank. A closure cap 3 isthreaded downwardly on the neck 2, in the usual manner.

p A split clamping ring 4 encircles the neck 2 below the'threaded portion thereof and has its adjacent front end provided'with'upstanding ears or lugs 5 having transverse :endsrigidlyconnected tolthe'ring l3xlAswill 00 clainping ringthrough the inedijf'n of a pair of downwair ito "seat on; the platform constituted by the i "extensions 8- and- 9"and receive'f the locking p'ost 'll therein {for securingthe forward fp'ortiori, of the clam ing ring 4 a-nd their" g g13 "together l he-lock l6 is provide n -i'ts upper 'base,"with a key 'receiving' o-peni ng'fl wand when thedeviceis unlocked the' ring 13 cap 3'onthepivotpin15'.
